Dual-energy photon counting was performed using an energy-selecting device (ESD) and a cadmium telluride detector. The ESD is used to determine a low-energy range for computed tomography (CT) and consists of two comparators and a microcomputer (MC).

In the near-infrared-ray computed tomography (NIR-CT) scanner, NIR photons are produced from a light-emitting diode (LED) and detected using a visible-ray (VR) phototransistor (PT) and an infrared filter. The LED-peak wavelength is 850 nm in the livi
